RAILWAY-SWITCH.

SPECIFICATION forming'part of Letters Patent No. 501,112, dated July 11,1893.

Application iled April 21, 1892.

To all whom it may concern,.-

Be it known that we, LOUIS V. STEVENS, residing at Buffalo, county ofErie, State of New York, and JOHN R. MOTT, residing at Cleveland, in thecounty of Cuyahoga and State of Ohio, citizens of the United States,have invented new and useful Improvem entsin Railway-Switches, of whichthe following is a speciication.

This invention relates to a new and improved device for operatin grailway switches; and it consists in certain details of construction andcombinationof parts all of which are hereinafter fully described andspecifically claimed.

The invention is clearly shown in the accompanying drawings, whereon-Figure l is a perspective view of that portion of the mechanism which islocated between the railroadrails. The dotted lines represent thecurbing, or frame of the pit in which said mechanism is located. Fig. 2is a transverse section of the railroad-rails, and a switch-rail withthat portion of the mechanism which is directly connected therewith,also a frame located below, and supporting said parts. Fig. 3 is an edgeview of a transverse frame arranged below the central part of themechanism for supporting the mainlevers thereof. Fig. 4 is a plan of theunder side of the platform arranged above the operating ends of thelevers, showing also the under surfaces of the lever trips and means forretaining same in position. Fig. 5 is a plan of the upper side of theaforesaid platform, with openings in which the trips are adapted t0operate. Fig. 6 is a sectional View of the front platform of a car, withmechanism for operating the switch, from the car. Fig. 7 is -a verticalsection of Fig. 6 taken through one pair of the hinged levers.

On the drawings the dotted lines A, see Fig. 1, designate a curbing offrame arranged Within a pit located between the railroad rails for thereception of that portion of the mechanism which is connected with theswitch-rail.

B is a metal-frame arranged transversely, at or-about the center of thepit, so that its outwardly projecting ends b b shall rest under therails and be secured thereto over the Serial No. 430,115. (No model.)

stringers C. C. in order that the proper position of the frame B.carrying the operative parts may be assured in case the stringers shouldsink away from the rails.

The lower portion of the frame B has a pair of journal-boxes D, D',riveted, or otherwise secured thereto, for receiving the fulcrumpins d dof a pair of levers E, E', to the forward ends of which are pivotallyconnected the rods F, F', each having a pair of plates f, f', hinged, orpivoted in the upper ends thereof, as shown atf,f, in Fig. l.

The letter G, designates a plate, or platform, which forms a cover forthe forward end of the pit. This platform is provided with tworectangularopenings g g within which the hinged-platesff are adapted tooperate.

The outer end of each hinged-plate f, is provided on its under side vtha stirrup h to receive one of the projections t' c" of theplates l, l,which are arranged under the platform G, as shown in Fig. 4, to preventdisplacement of the hinged plates f, during the operation of same.

The opposite, or rear ends of the levers E, E', are connected by meansof links Z Z with the opposite ends of a triple-armed crank M, which isjournaled in abox m, that is secured in the bottom of a metal frame Narranged across the pit, with upper projecting ends, resting on thestringers, C C', and with the railroad-rails secured on said projectingends, as shown in Fig. 2. The central arm of the triple-crank projectsupward and is connected by a link o, with a lever p that is pivoted in abox q, so that the upper-slotted end of said lever p, shall engage thedownwardly projecting-pin 1,0f the switch-rail 2.

The end platform P, of-each car, see Fig. 6, is provided at each side ofthe longitudinal center thereof, with a device through theinstrumentality of which, the driver or other attendant may operate theswitch as desired, without checking the speed of the car, or dismountingfrom same. These devices consist each, of a vertical standard 3, havinga camlever 4 pivoted in the upper end'thereof, a link 5 pivotallyconnected with said lever, a hanger 6 secured to the under side of theplatform at a point below the vertical-stand- IOO ard thereof, a lever 7pivoted in said hanger, a roller or idler 8 journaled in the lower endof the lever 7, and a series of perforations in the upper end of lever 7for receiving a pin 9 whereby the lower end of the link 5 is ad justablysecured, as the height of the car may require.

In the operation of our invention the driver has simply to pressdownward the handle of one of the levers 4. This movement depresses theroller or idler of said device causing same to be brought into positionfor engaging the hinged plates necessary to shift the switch rail asdesired; forinstance it it is desired to throw the point of theswitch-rail to the right the lever 4 on the right hand side of the caris thrown down causing the attached roller or idler to be brought downso as to engage the right hand set of hinged plates f, f', which onbeing forced down carries with them the rod F. This depresses theattached end of the lever E, throwing its forward end upward and tippingwith it the triple-armed crank M, to the left. This motion throws thelower end of the pivoted lever 19 to the left and consequently moves theswitch rail 2 attached to its upper end to the right as desired. Duringthe operation just described the left hand set of hinged plates ff. arethrown up ready for engagement with the left hand roller on the car whenthe switch rail is to be thrown back in the opposite direction or to theleft.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, ism 1. In a railway-switch, the combinationot' the pivoted levers E E', triple armed-crank M, links Z, Z', o;pivoted lever p, and the switchrail having a downwardly projecting-pin,as described, with the rods F F', connecting hinged-plates ff', and theplatform G having rectangular openin gs therein, substantially as andfor the purpose set forth.

2. The device for operating the switch rail 2 having a downwardlyprojecting pin, consistingof the pivoted lever p. the triple armed crankM. the link c adj ustably connecting the lever p and crank M. the linksZ Z rocking levers E. E. rods F. F hinged platesff pivoted to said rodsand platform G. having rectangular openings therein all combined andadapted to be operated by a device upon the car for depressing saidhinged plates substantially as shown and described.

3. A device for operating a switch rail consisting essentially of a pairof separately pivoted levers located below the surface the arms on oneside of the pivots beingconnected with devices at the surface fordepressing their outer ends and the outer ends of the arms on theopposite side being pivotally connected to opposite arms of a pivotedtriple armed crank the central arm ot' which being connected to andmoving the switch rail substantially as shown and described. i

In testimony whereof we affix our signatures in presence of twowitnesses.
